Robertshaw 4200-005 Gas Thermostat

The Robertshaw 4200-005 is a heavy-duty commercial gas thermostat engineered for high-capacity temperature regulation in demanding kitchen environments. This FDO gas thermostat features a broad temperature range of 150°F to 550°F (66°C to 288°C), making it a versatile choice for deck ovens, convection units, and standard ranges. Utilizing a 1/2" pipe connection and a 48-inch capillary tube, this control ensures precise thermal management for medium to large-scale cooking equipment. The unit operates with a modulating snap-acting bypass, allowing for both the modulation of the main gas supply and sharp bypass control under a single thermostatic action. Designed for durability, the sensing bulb measures 3/16" x 14-3/4" and is finished in nickel-plated copper to resist corrosion and thermal stress. The Robertshaw 4200 series is built with front-accessible, slotted pilot and bypass adjustment keys, simplifying calibration for field technicians during routine maintenance or initial setup.

• Versatile 4-Way Mounting: Flexible installation positions allow for seamless integration into various equipment chassis.
• High Temperature Range: Rated up to 550°F, ideal for high-heat baking ovens and specialized commercial cooking equipment.
• Precise Control: Modulating gas flow provides consistent heat levels, reducing temperature fluctuations that impact food quality.
• Durable Construction: Features heat-resistant materials and a rugged body type #2 design for long-term reliability in hot line environments.
• Service Friendly: Front-access adjustment keys allow technicians to tune pilot and bypass settings without complete disassembly.

Is the Robertshaw 4200-005 compatible with different gas types?
This model is primarily designed for natural gas systems. For LP conversion or specific pilot outlet configurations, check the technical cross-reference for the appropriate orifice and regulator settings.

What is the purpose of the 48-inch capillary on this model?
The extended 48-inch capillary provides necessary reach for larger deck ovens and convection units where the sensing bulb must be placed deep within the cabinet while the control dial remains accessible.

Does this thermostat include the dial?
Standard 4200-005 units are often sold as the control body and sensing element. Slip-fit dials for the 4200 series are typically matched to the temperature range and may need to be ordered separately if the original is damaged.
